HVAC Case Study
Northshore Apartments, Palm Beach, QLD

Challenges

• Corrosive Environment: The coastal location posed a significant risk of salt-induced corrosion, threatening the longevity of conventional AC systems.
• Limited Ceiling Space: Architectural constraints restricted ceiling cavity depth, making standard indoor unit placement unfeasible.
• Wardrobe Installation: Indoor units had to be installed within wardrobes, necessitating ultra-compact designs.
• Roof-Mounted Condensers: External units were required to be roof-mounted, introducing long piping runs that exceeded the limits of many conventional systems
